Cablevision founder Chuck Dolan is turning down the heat on his efforts to gain even more control of the Long Island-based cable giant.

Having lost his bid to keep funding his pet satellite project Voom, Dolan yesterday said he would not go forward with a plan to reduce the size of the board at the company’s upcoming annual meeting in May.

In a regulatory filing with the Securities and Exchange Commission, the company said Dolan was no longer planning to reduce the number of board members from 15 to 12 and give himself the right to elect 75 percent of Cablevision’s board of directors, instead of his current 60 percent.

He had planned to essentially fire three board members who had been elected by minority shareholders.

The move marks a retreat for Dolan, who for much of the year has been in a bruising battle with his son, CEO Jimmy Dolan, over the future of Voom.

In March, the elder Dolan replaced four members of the board who had opposed his plan for the company to keep funding the money-losing Voom.

He replaced them with media industry veterans, including Liberty Media chief John Malone and former Viacom head Frank Biondi.

At the time, Dolan also said he plans to add Brian Sweeney, his son-in-law, to the board at the annual meeting on May 7. It is unclear from yesterday’s filing if he still plans to add Sweeney to the board.

After the board voted to halt funding for Voom, Chuck Dolan formed a private company and sought to buy many of the unit’s assets.

He ultimately failed, and earlier this month Cablevision said it was finally shutting down the service on April 30.

The company sold its satellite to EchoStar for about $200 million – a deal that Dolan tried to block in a filing with the Federal Communications Commission.

Last year, Voom lost $661.4 million on revenue of $14.9 million, including $355 million in write-downs.

Last week, Cablevision lost in its bid for bankrupt cable operator Adelphia when a bankruptcy court judge approved an $18 billion deal with Time Warner and Comcast.

However, some say Cablevision may try to break up that deal – an expensive proposition given that the judge in the case approved approximately $400 million in break-up fees.
